"Hot

- spot analysis" means an estimation of likely future localized CO and PM 10 pollutant concentrations and a comparison of those concentrations to the national ambient air quality standar ds. Pollutant concentrations to be estimated should be based on the total emissions burden which may result from the implementation of a single, specific project, summed together with future background concentrations (which can be estimated using the ratio of future to current traffic multiplied by the ratio of future to current emission factors) expected in the area. The total concentration shall be estimated and analyzed at appropriate receptor locations in the area substantially affected by the project. Hot

- spot analysis assesses impacts on a scale smaller than the entire nonattainment or maintenance area, including, for example, congested roadway intersections and highways or transit terminals, and uses an air quality dispersion model to determine the ef fects of emissions on air quality."Incomplete data area" means any ozone nonattainment area which the U.S. Environmental Protection Agency has classified, in 40 CFR Part 81, as an incomplete data area.

Transportation plans adopted after January 1, 1995, in serious, severe, or extreme ozone nonattainment areas and in serious carbon monoxide nonattainment areas shall spec ifically describe the transportation system envisioned for certain future years which shall be called horizon years. 1. The agency or organization developing the transportation plan may choose any years to be horizon years, subject to the following restri ctions:

a. Horizon years may be no more than 10 years apart. b. The first horizon year may be no more than 10 years from the base year used to validate thetransportation demand planning model.

c. If the attainment year is in the time span of the transp ortation plan, the attainment year shall be a horizon year. d. The last horizon year shall be the last year of the transportation plan's forecast period. 2. For these horizon years: a. The transportation plan shall quantify and document the demographic and employment factors influencing expected transportation demand, including land use forecasts, in accordance with implementation plan provisions and 9VAC5

- 150

- 130; b. The highway and transit system shall be described in terms of the regional ly significant additions or modifications to the existing transportation network which the transportation plan envisions to be operational in the horizon years. Additions and modifications to the highway network shall be sufficiently identified to indicate intersections with existing regionally significant facilities, and to determine their effect on route options between transportation analysis zones. Each added or modified highway segment shall also be sufficiently identified in terms of its design concep t and design scope to allow modeling of travel times under various traffic volumes, consistent with the modeling methods for area

- wide transportation analysis in use by the MPO. Transit facilities, equipment, and services envisioned for the future shall be identified in terms of design concept, design scope, and operating policies sufficiently to allow modeling of their transit ridership. The description of additions and modifications to the transportation network shall also be sufficiently specific to show that there is a reasonable relationship between expected land use and the envisioned transportation system; and c. Other future transportation policies, requirements, services, and activities, including intermodal activities, shall be described.
B. Ozon e or CO nonattainment areas which are reclassified from moderate to serious shall meet the requirements of subsection A of this section within two years from the date of reclassification.C. Transportation plans for other areas shall meet the requirements of subsection A of this section at least to the extent it has been the previous practice of the MPO to prepare plans which meet those requirements. Otherwise, transportation plans shall describe the transportation system envisioned for the future specific ally enough to allow determination of conformity according to the criteria and procedures of 9VAC5

- 190. Criteria and procedures: latest emissions model. A. The conformity determination shall be based on the latest emission estimation m odel available. This criterion applies during all periods. It is satisfied if the most current version of the motor vehicle emissions model specified by EPA for use in the preparation or revision of implementation plans in that state or area is used for th e conformity analysis. Where EMFAC is the motor vehicle emissions model used in preparing or revising the applicable implementation plan, new versions shall be approved by EPA before they are used in the conformity analysis.
B. EPA shall consult with USDO T to establish a grace period following the specification of any new model. 1. The grace period shall be no less than three months and no more than 24 months after notice ofavailability is published in the Federal Register. 2. The length of the grace pe riod shall depend on the degree of change in the model and the scope of

re - planning likely to be necessary by MPOs in order to assure conformity. If the grace period will be longer than three months, EPA shall announce the appropriate grace period in the F ederal Register. C. Conformity analyses for which the emissions analysis was begun during the grace period or before the Federal Register notice of availability of the latest emission model may continue to use the previous version of the model for transportation plans and TIPs. The previous model may also be used for projects if the analysis was begun during the grace period or before the Federal Register notice of availability, provided no more than three years have passed since the draft environmental document was issued.

The transportation plan, TIP, or FHWA/FTA project which is not from a conforming plan and TIP shall provide for the timely implementation of TCMs from the applicable implementation plan. This criteri on applies during all periods. B. For transportation plans, this criterion is satisfied if the following two conditions are met: 1. The transportation plan, in describing the envisioned future transportation system, provides for the timely completion or implementation of all TCMs in the applicable implementation plan which are eligible for funding under Title 23 USC or the Federal Transit Act, consistent with schedules included in the applicable implementation plan. 2. Nothing in the transportation plan interferes with the implementation of any TCM in the applicable implementation plan. C. For TIPs, this criterion is satisfied if the following conditions are met: 1. An examination of the specific steps and funding source(s) needed to fully implement eac h TCM indicates that TCMs which are eligible for funding under Title 23 USC or the Federal Transit Act are on or ahead of the schedule established in the applicable implementation plan, or, if the TCMs are behind the schedule established in the applicable implementation plan, the MPO and USDOT have determined that past obstacles to implementation of the TCMs have been identified and have been or are being overcome, and that all state and local agencies with influence over approvals or funding for TCMs are
g iving maximum priority to approval or funding of TCMs over other projects within their control, including projects in locations outside the nonattainment or maintenance area. 2. If TCMs in the applicable implementation plan have previously been programmed for federal funding but the funds have not been obligated and the TCMs are behind the schedule in the implementation plan, then the TIP cannot be found to conform if the funds intended for those TCMs are reallocated to projects in the TIP other than TCMs, or if there are no other TCMs in the TIP, if the funds are reallocated to projects in the TIP other than projects which are eligible for federal funding under ISTEA's Congestion Mitigation and Air Quality Improvement Program.3. Nothing in the TIP may in terfere with the implementation of any TCM in the applicable implementation plan. D. For FHWA/FTA projects which are not from a conforming transportation plan and TIP, this criterion is satisfied if the project does not interfere with the implementation o f any TCM in the applicable implementation plan.

Determine the analysis years for which emissions are to be estimated. Analysis years shall be no more than 10 years apart. The first analysis year shall be no later than 1996 (for NO 2 areas) or four years and six months following the date of designation (for PM 10 areas). The second analysis year shall be either the attainment year for the area, or if the attainment year is the same as the first analysis year or earlier, the second analysis year shall be at least five years beyond the first analysis year.

- 380. The analysis shall address the periods between the analysis years and the periods between 1990, the first milestone year (if any), and the first of the analysis years. Emissions in miles tone years which are between the analysis years may be determined by interpolation. 4. Demonstrate that the regional PM 10 emissions and PM 10 precursor emissions, where applicable, (for PM 10 nonattainment areas) and NO X emissions (for NO 2 nonattainment are as) predicted in the "action" scenario are less than the emissions predicted from the "baseline" scenario in each analysis year, and that this can reasonably be expected to be true in the periods between the first milestone year (if any) and the analysis y ears.

Determine the baseline regional emissions of PM 10 and PM 10 precursors, where applicable (for
PM 10 nonattainment areas) and NO X (for NO 2 nonattainment areas) from highway and transit sources. Baseline emissions are those estimated to have occurred during calendar year 1990, unless the implementation plan revision required by this regulation defines the baseline emissions for a PM 10 area to be those occurring in a different calendar year for which a baseline emissions inventory was developed for the purpos e of developing a control strategy implementation plan. 2.

A. A TIP shall contribute to emission reductions or shall not increase emissions in PM 10 and NO 2 nonat tainment areas. This criterion applies only during the interim and transitional periods. It applies to the net effect on emissions of all projects contained in a new or revised TIP. This criterion may besatisfied if the requirements of either subsection B or C of this section are met. B.

- 360. Transition from the interim period to the control strategy period. A. For areas that submit control strategy implementation plans the following requirements shall be
met. 1. The transportation plan and TIP must be demonstrated to conform by 18 months from the date of the state's initial submission to EPA of each control strategy implementation plan establishing a motor vehicle emissions budget. If conformity is not determined by 18 months from the date of submission of such control strategy implementation plan, the conformity status of the transportation p lan and TIP will lapse, and no new project

- level conformity determinations may be made until the transportation plan andTIP have been demonstrated to conform. 2. For areas not yet in the control strategy period for a given pollutant, conformity shall be demonstrated using the motor vehicle emissions budget(s) in a submitted control strategy implementation plan revision for that pollutant beginning 90 days after submission unless EPA declares such budget or budgets inadequate for transportation conformity purposes. The motor vehicle emissions budget or budgets may be used to determine conformity during the first 90 days after its submission if EPA agrees that the budget or budgets are adequate for conformity purposes. B. For areas that submit a plan and th e plan is disapproved: 1. If EPA disapproves the submitted control strategy implementation plan revision and so notifies the state, MPO, and USDOT, which initiates the sanction process under § 179 or 110(m) of the federal Clean Air Act, the conformity sta tus of the transportation plan and TIP shall lapse 120 days after EPA's disapproval, and no new project

- level conformity determinations may be made. No new transportation plan, TIP, or project may be found to conform until another control strategy implemen tation plan revision fulfilling the same federal Clean Air Act requirements is submitted and conformity to this submission is determined. 2. Notwithstanding subdivision 1 of this subsection, if EPA disapproves the submitted control strategy implementation plan revision but makes a protective finding, the conformity status of the transportation plan and TIP shall lapse on the date that highway sanctions as a result of the disapproval are imposed on the nonattainment area under § 179(b)(1) of the federal Cle an Air Act. No new transportation plan, TIP, or project may be found to conform until another control strategy implementation plan revision fulfilling the same federal Clean Air Act requirements is submitted and conformity to this submission is determined. C. For areas where EPA notifies the state, MPO, and USDOT of the state's failure to submit or submission of an incomplete control strategy implementation plan revision, which initiates the sanction process under § 179 or 110(m) of the federal Clean Air A ct, the conformity status of the transportation plan and TIP shall lapse on the date that highway sanctions are imposed on the nonattainment area for such failure under § 179(b)(1) of the federal Clean Air Act, unless the failure has been remedied andackn owledged by a letter from the EPA Regional Administrator. D. When EPA promulgates a federal implementation plan that contains motor vehicle emissions budget or budgets as a result of a state failure, the conformity lapse imposed by this section because of that state failure is removed. E. For FHWA/FTA projects, if the currently conforming transportation plan and TIP have not been demonstrated to conform according to transitional period criteria and procedures, the requirements of subdivisions 1 and 2 of t his subsection shall be met. 1. Before a FHWA/FTA project which is regionally significant and increases single

- occupant vehicle capacity (a new general purpose highway on a new location or adding general purpose lanes) may be found to conform, the DEQ sha ll be consulted on how the emissions which the existing transportation plan and TIP's conformity determination estimates for the "action" scenario (as required by 9VAC5

- 150

- 300 through 9VAC5

- 150

- 350) compare to the motor vehicle emissions budget in the imp lementation plan submission or the projected motor vehicle emissions budget in the implementation plan under development. 2. In the event of unresolved disputes on the project

- level conformity determinations, the DEQ Director may escalate the issue to the Governor consistent with the procedure in 9VAC5

- 150

- 130 D, which applies for any DEQ comments on a conformity determination. F. For the redetermination of conformity of the existing transportation plan and TIP according to the transitional period criteri a and procedures, the requirements of subdivisions 1 and 2 of this subsection shall be met. 1. The redetermination of the conformity of the existing transportation plan and TIP according to transitional period criteria and procedures (as required by subdi vision A 1 of this section and subsection D of this section) does not require new emissions analysis and does not have to satisfy the requirements of 9VAC5

- 150

- 180 and 9VAC5

- 150

- 190 if:

a. The control strategy implementation plan revision submitted to EPA uses the MPO'smodeling of the existing transportation plan and TIP for its projections of motor vehicle

emissions; and b. The control strategy implementation plan does not include any transportation projects which are not included in the transportation plan and TIP. 2. A redetermination of conformity as described in subdivision 1 of this subsection is not considered a conformity determination for the purposes of 9VAC5

- 150

- 120 B 4 or C 4 regarding the maximum intervals between conformity determinations. Conformity shall be determined according to all the applicable criteria and procedures of 9VAC5

- 150

- 170 within three years of the last determination which did not rely on subdivision 1 of this subsection. G. For nonattainment areas which are not required to demonstrate reasonable further progress and attainment, if an area listed in 9VAC5

- 150

- 440 submits a control strategy implementation plan revision, the requirements of subsections A and E of this section apply. Because the areas listed in 9VAC5

- 150

- 440 are not required to demonstrate reasonable further progress and attainment, the provisions of subsections B and C of this section do not apply to these areas. H. For maintenance plans, if a control strategy implementation plan revision is not submitted to EPA but a maintenance plan required by § 175A of the federal Clean Air Act is submitted to EPA, the requirements of subsection A or D of this section apply, with the maintenance plan submission treated as a "control strategy implementation plan revision" for the purposes of those requirements.

The project is included in the regional emissions analysis supporting the currently conforming TIP's conformity determination, even if the project is not strictly "included" in the TIP for the pu rposes of MPO project selection or endorsement, and the project's design concept and scope have not changed significantly from those which were included in the regional emissions analysis, or in a manner which would significantly impact use of the facility ; 3. During the control strategy or maintenance period, the project is consistent with the motor vehicle emissions budget(s) in the applicable implementation plan consistent with the requirements of 9VAC5

- 150

- 280; 4. During Phase II of the interim period, the project contributes to emissions reductions or does not increase emissions consistent with the requirements of 9VAC5

- 380. Procedures for determining regional transportation
- related emissions. A. With regard to conducting regional analyses for transportation

- related emissions, the requirements of this subsection shall be met.1. The regional emissions analysis for the transportation plan, TIP, or project not from a conforming plan and TIP shall include all regionally significant projects expected in the nonattainment or maintenance area, including FHWA/FTA projects proposed in the tr ansportation plan and TIP and all other regionally significant projects which are disclosed to the MPO as required by 9VAC5

- 150

- 130. Projects which are not regionally significant are not required to be explicitly modeled, but VMT from the projects shall be estimated in accordance with reasonable professional practice. The effects of TCMs and similar projects that are not regionally significant may also be estimated in accordance with reasonable professional practice. 2. The emissions analysis may not inclu de for emissions reduction credit any TCMs which have been delayed beyond the scheduled date(s) until such time as implementation has been assured. If the TCM has been partially implemented and it can be demonstrated that it is providing quantifiable emiss ion reduction benefits, the emissions analysis may include that emissions reduction credit. 3. Emissions reduction credit from projects, programs, or activities which require a regulation in order to be implemented may not be included in the emissions ana lysis unless the regulation is already adopted by the enforcing jurisdiction. Adopted regulations are required for demand management strategies for reducing emissions which are not specifically identified in the applicable implementation plan, and for
cont rol programs which are external to the transportation system itself, such as tailpipe or evaporative emission standards, limits on gasoline volatility, inspection and maintenance programs, and oxygenated or reformulated gasoline or diesel fuel. A regulator y program may also be considered to be adopted if an opt

- in to a federally enforced program has been approved by EPA, if EPA has promulgated the program (if the control program is a federal responsibility, such as tailpipe standards), or if the federal Cle an Air Act requires the program without need for individual state action and without any discretionary authority for EPA to set its stringency, delay its effective date, or not implement the program. 4. Notwithstanding subdivision 3 of this subsection, du ring the transitional period, control measures or programs which are committed to in an implementation plan submission as described in 9VAC5

- 150

- 260 through 9VAC5

- 150

- 280, but which has not received final EPA action in the form of a finding ofincompletene ss, approval, or disapproval may be assumed for emission reduction credit for the purpose of demonstrating that the requirements of 9VAC5

- 150

- 260 through 9VAC5

- 150

- 280 are satisfied. 5. A regional emissions analysis for the purpose of satisfying the requi rements of 9VAC5

- 150

- 300 through 9VAC5

- 150

- 320 may account for the programs in subdivision 4 of this subsection, but the same assumptions about these programs shall be used for both the "baseline" and "action" scenarios. 6. Ambient temperatures shall be c onsistent with those used to establish the emissions budget in the applicable implementation plan. Factors other than temperatures, for example, the fraction of travel in a hot stabilized engine mode, may be modified after interagency consultation accordin g to 9VAC5

- 150

- 130 if the newer estimates incorporate additional or more geographically specific information or represent a logically estimated trend in the factors beyond the period considered in the applicable implementation plan. B. For serious, severe , and extreme ozone nonattainment areas and serious carbon monoxide areas after January 1, 1995, estimates of regional transportation

- related emissions used to support conformity determinations shall be made according to procedures which meet the requireme nts in subsection B of this section.
1. A network

- based transportation demand model or models relating travel demand and transportation system performance to land

- use patterns, population demographics, employment, transportation infrastructure, and transp ortation policies shall be used to estimate travel within the metropolitan planning area of the nonattainment area. The model shall possess the following attributes:

a. The modeling methods and the functional relationships used in the model(s) shall in al l respects be in accordance with acceptable professional practice, and reasonable for purposes of emission estimation;
b. The network

- based model(s) shall be validated against ground counts for a base year that is not more than 10 years prior to the date of the conformity determination. Land use, population, and other inputs shall be based on the best available information and appropriate to the validation base year;c. For peak

- hour or peak

- period traffic assignments, a capacity sensitive assignment

meth odology shall be used;
d. Zone

- to

- zone travel times used to distribute trips between origin and destination pairs shall be in reasonable agreement with the travel times which result from the process of assignment of trips to network links. Where use of tr ansit currently is anticipated to be a significant factor in satisfying transportation demand, these times should also be used for modeling mode splits;
e. Free

- flow speeds on network links shall be based on empirical observations;
f. Peak and off

- peak t ravel demand and travel times shall be provided; g. Trip distribution and mode choice shall be sensitive to pricing, where pricing is a significant factor, if the network model is capable of such determinations and the necessary information is available; h. The model(s) shall utilize and document a logical correspondence between the assumed scenario of land development and use and the future transportation system for which emissions are being estimated. Reliance on a formal land

- use model is not specifica lly required but is encouraged; i. A dependence of trip generation on the accessibility of destinations via the transportation system (including pricing) is strongly encouraged but not specifically required, unless the network model is capable of such det erminations and the necessary information is available; j. A dependence of regional economic and population growth on the accessibility of destinations via the transportation system is strongly encouraged but not specifically required, unless the network model is capable of such determinations and the necessary information is available; and
k. Consideration of emissions increases from construction

- related congestion is not specifically required. 2. Highway Performance Monitoring System (HPMS) estimates of vehicle miles traveled shall beconsidered the primary measure of vehicle miles traveled within the portion of the nonattainment or maintenance area and for the functional classes of roadways inc luded in HPMS, for urban areas which are sampled on a separate urban area basis. A factor (or factors) shall be developed to reconcile and calibrate the network

- based model estimates of vehicle miles traveled in the base year of its validation to the HPMS estimates for the same period, and these factors shall be applied to model estimates of future vehicle miles traveled. In this factoring process, consideration shall be given to differences in the facility coverage of the HPMS and the modeled network descr iption. Departure from these procedures is permitted with the concurrence of USDOT and EPA.
3. Reasonable methods shall be used to estimate nonattainment area vehicle travel on off

- network roadways within the urban transportation planning area, and on roa dways outside the urban transportation planning area. 4. Reasonable methods in accordance with good practice shall be used to estimate traffic speeds and delays in a manner that is sensitive to the estimated volume of travel on each roadway segment
repres ented in the network model. C. For areas which are not serious, severe, or extreme ozone nonattainment areas or serious carbon monoxide areas, or before January 1, 1995, the requirements of this subsection shall be met. 1. Procedures which satisfy some o r all of the requirements of subsection B of this section shall be used in all areas not subject to subsection B of this section in which those procedures have been the previous practice of the MPO. 2. Regional emissions may be estimated by methods which do not explicitly or comprehensively account for the influence of land use and transportation infrastructure on vehicle miles traveled and traffic speeds and congestion. The methods shall account for VMT growth by extrapolating historical VMT or projecting future VMT by considering growth in population and historical growth trends for vehicle miles travelled per person. These methods shall also consider future economic activity, transit alternatives, and transportation system policies.
D. This subsection a pplies to any nonattainment or maintenance area or any portion thereof whichdoes not have a metropolitan transportation plan or TIP and whose projects are not part of the emissions analysis of any MPO's metropolitan transportation plan or TIP (because the nonattainment or maintenance area or portion thereof does not contain a metropolitan planning area or portion of a metropolitan planning area and is not part of a Metropolitan Statistical Area or Consolidated Metropolitan Statistical Area which is or cont ains a nonattainment or maintenance area). 1. Conformity demonstrations for projects in these areas may satisfy the requirements of 9VAC5

- 150

- 280, 9VAC5

- 150

- 320, and 9VAC5

- 150

- 350 with one regional emissions analysis which includes all the regionally sign ificant projects in the nonattainment or maintenance area (or portion thereof). 2. The requirements of 9VAC5

- 150

- 280 shall be satisfied according to the procedures in 9VAC5

- 150

- 280 C, with references to the "transportation plan" taken to mean the statewid e transportation plan. 3. The requirements of 9VAC5

- 150

- 320 and 9VAC5

- 150

- 350 which reference "transportation plan" or "TIP" shall be taken to mean those projects in the statewide transportation plan or statewide TIP which are in the nonattainment or main tenance area (or portion thereof). 4. The requirement of 9VAC5

- 150

- 370 B shall be satisfied if: a. The project is included in the regional emissions analysis which includes all regionally significant highway and transportation projects in the nonattainme nt or maintenance area (or portion thereof) and supports the most recent conformity determination made according to the requirements of 9VAC5

- 150

- 280, 9VAC5

- 150

- 320, or 9VAC5

- 150

- 350 (as modified by subdivisions 2 and 3 of this subsection), as appropriate for the time period and pollutant; and b. The project's design concept and scope have not changed significantly from those which were included in the regional emissions analysis, or in a manner which would significantly impact use of the facility.
E. For PM 10 from construction

- related fugitive dust, the requirements of this subsection shall be met. 1. For areas in which the implementation plan does not identify construction

- related fugitive PM 10 as a contributor to the nonattainment problem, the fugitive PM 10 emissions associated with highway and transitproject construction are not required to be considered in the regional emissions analysis.
2. In PM 10 nonattainment and maintenance areas with implementation plans which identify construction

- related fug itive PM 10 as a contributor to the nonattainment problem, the regional PM 10 emissions analysis shall consider construction

- related fugitive PM 10 and shall account for the level of construction activity, the fugitive PM 10 control measures in the applicable implementation plan, and the dust

- producing capacity of the proposed activities. Statutory Authority § 10.1

- 150

- 130 and with the approval of the EPA Regional Administrator, these models, data bases, and other requirements are determined to be inappropriate: 1. For projects in or affecting l ocations, areas, or categories of sites which are identified in the applicable implementation plan as sites of current violation or possible current violation;
2. For those intersections at Level

- Service D, E, or F, or those that will change to Level

- o f

- Service D, E, or F because of increased traffic volumes related to a new project in the vicinity; 3. For any project involving or affecting any of the intersections which the applicable implementation plan identifies as the top three intersections in th e nonattainment or maintenance area based on the highest traffic volumes; 4. For any project involving or affecting any of the intersections which the applicable implementation plan identifies as the top three intersections in the nonattainment or maintenance area based on the worstLevel

- of

- Service; and 5. Where use of the "guideline" models is practicable and reasonable given the potential for violations.
B. In cases other than those described in subse ction A of this section, other quantitative methods may be used if they represent reasonable and common professional practice.
C. CO hot

- spot analyses shall include the entire project, and may be performed only after the major design features which shall significantly impact CO concentrations have been identified. The background concentration can be estimated using the ratio of future

- to

- current traffic multiplied by the ratio of future

to

- current emission factors.
D. PM 10 hot

- spot analysis shall be perfo rmed for projects which are located at sites at which violations have been verified by monitoring, and at sites which have essentially identical vehicle and roadway emission and dispersion characteristics (including sites near one at which a violation has been monitored). The projects which require PM 10 hot

- spot analysis shall be determined through the interagency consultation process required in 9VAC5

- 150

- 130. In PM 10 nonattainment and maintenance areas, new or expanded bus and rail terminals and transfer points which increase the number of diesel vehicles congregating at a single location require hot

- spot analysis. USDOT may choose to make a categorical conformity determination on bus and rail terminals or transfer points based on appropriate modeling of v arious terminal sizes, configurations, and activity levels. The requirements of this subsection for quantitative hot

- spot analysis shall not take effect until EPA releases modeling guidance on this subject and announces in the Federal Register that these r equirements are in effect.
E. Hot

- spot analysis assumptions shall be consistent with those in the regional emissions analysis for those inputs which are required for both analyses.
F. PM 10 or CO mitigation or control measures shall be assumed in the hot

- spot analysis only where there are written commitments from the project sponsor, operator or both, to the implementation of the measures, as required by 9VAC5

- 150

- 410 A.
G. CO and PM 10 hot

- spot analyses are not required to consider construction

- 400. Using the motor vehicle emissions budget in the applicable implementation plan (or implementation plan submission). A. In interpreting an applicable implementation plan (or implementation plan submission) with respect to its motor vehicle emissions budget or budgets, th e MPO and USDOT may not infer additions to the budget or budgets that are not explicitly intended by the implementation plan (or submission). Unless the implementation plan explicitly quantifies the amount by which motor vehicle emissions could be higher

w hile still allowing a demonstration of compliance with the milestone, attainment, or maintenance requirement and explicitly states an intent that some or all of this additional amount should be available to the MPO and USDOT in the emission budget for conf ormity purposes, the MPO may not interpret the budget to be higher than the implementation plan's estimate of future emissions. This applies in particular to applicable implementation plans (or submissions) which demonstrate that after implementation of

co ntrol measures in the implementation plan:
1. Emissions from all sources shall be less than the total emissions that would be consistent with a required demonstration of an emissions reduction milestone;
2. Emissions from all sources shall result in achi eving attainment prior to the attainment deadline or ambient concentrations in the attainment deadline year shall be lower than needed to demonstrate attainment, or both; or 3. Emissions shall be lower than needed to provide for continued maintenance.B. If an applicable implementation plan submitted before November 24, 1993, demonstrates that emissions from all sources shall be less than the total emissions that would be consistent with attainment and quantifies that "safety margin," the state may submit a SIP revision which assigns some or all of this safety margin to highway and transit mobile sources for the purposes of conformity. The SIP revision, once it is endorsed by the Governor and has been subject to a public hearing, may be used for the
purpos es of transportation conformity before it is approved by EPA. C. A conformity demonstration shall not trade emissions among budgets which the applicable implementation plan (or implementation plan submission) allocates for different pollutants or precurso rs, or among budgets allocated to motor vehicles and other sources, without a SIP revision or a SIP which establishes mechanisms for the trades. D. If the applicable implementation plan (or implementation plan submission) estimates future emissions by geo graphic subarea of the nonattainment area, the MPO and USDOT are not required to consider this to establish subarea budgets, unless the applicable implementation plan (or implementation plan submission) explicitly indicates an intent to create the subarea budgets for the purposes of conformity. E. If a nonattainment area includes more than one MPO, the SIP may establish motor vehicle emissions budgets for each MPO, or else the MPOs shall collectively make a conformity determination for the entire nonattain ment area.

Prior to determining that a transportation project is in conformity, the MPO, other recipient of fundsdesignated under Title 23 USC or the Federal Transit Act, FHWA, or FTA shall obtain from the project sponsor, operator or both, written commitments to implement in the construction of the project and operation of the resulting facility or service any project

D. During the control strategy and maintenance perio ds, if the MPO or project sponsor believes the mitigation or control measure is no longer necessary for conformity, the project sponsor or operator may be relieved of its obligation to implement the mitigation or control measure if it can demonstrate that the requirements of 9VAC5

Notwithstanding the other requ irements of this chapter, highway and transit projects of the types listed in Table 2 are exempt from the requirement that a conformity determination be made. The projects may proceed toward implementation even in the absence of a conforming transportation plan and TIP. A particular action of the type listed in Table 2 is not exempt if the MPO in consultation with other agencies (see 9VAC5

- 150

- 130 C 1 c), the EPA, and the FHWA (in the case of a highway project) or the FTA (in the case of a transit project) concur that it has potentially adverse emissions impacts for any reason. States and MPOs shall ensure that exempt projects do not interfere with TCM implementation.
